+## Thank you for sending in a pull request, here's some tips to get started!
+
+(Please delete all these tips and replace with your text)
+
+- Before starting on some new big chunk of code, it it is optional but highly recommended to open an issue first
+  to say "hey, I think this idea X should be implemented and I'm starting work on it. My general plan is Y, any feedback
+  is appreciated." This will allow other devs to potentially save you time by not accidentially duplicating work etc...
+- Please do not check in files that don't have real changes
+- Please do not reformat lines that you didn't have to change the code on
+- We recommend using the [Visual Studio Code](https://platformio.org/install/ide?install=vscode) editor and the 'clang-format' extension,
+  because automatically follows our indentation rules and it's auto reformatting will not cause spurious changes to lines.
+- If your PR fixes a bug, mention "fixes #bugnum" somewhere in your pull request description.
+- If your other co-developers have comments on your PR please tweak as needed.

 ## Supported hardware
-We currently support two brands of radios.  The [TTGO T-Beam](https://www.aliexpress.com/item/4000119152086.html) and the [Heltec LoRa 32](https://heltec.org/project/wifi-lora-32/).  Most users should buy the T-Beam and a 18650 battery (total cost less than $35).  Make
-sure to buy the frequency range which is legal for your country.  For the USA, you should buy the 915MHz version.  Getting a version that include a screen
-is optional, but highly recommended.
 
-See (meshtastic.org) for 3D printable cases.
+We currently support three models of radios.
 
-## Installing the firmware
-Prebuilt binaries for the supported radios is available in our [releases](https://github.com/geeksville/Meshtastic-esp32/releases).  Your initial installation has to happen over USB from your Mac, Windows or Linux PC.   Once our software is installed, all future software updates happen over bluetooth from your phone.
+- TTGO T-Beam (usually the recommended choice)
+  - [T-Beam V1.1 w/ NEO-6M - special Meshtastic version](https://www.aliexpress.com/item/4001178678568.html) (Includes built-in OLED display and they have **preinstalled** the meshtastic software)

+  - [3D Printable case](https://www.thingiverse.com/thing:3125854)
+  
+Note: The GPS and LoRa stock antennas should be placed in a way, that the GPS antenna faces the sky and the LoRa antenna radiates 360 degrees horizontally. For better GPS reception you might want to [upgrade the GPS antenna](https://meshtastic.discourse.group/t/the-importance-of-gps-antennas-and-request-to-3d-case-documentation-people/1505) and to properly align the antennas you might want to upgrade to a LoRa antenna that can be adjusted to radiate into the right directions.
+
+**Make sure to get the frequency for your country**
+
+- US/JP/AU/NZ/CA - 915MHz
+- CN - 470MHz
+- EU - 868MHz, 433MHz
+- full list of LoRa frequencies per region is available [here](https://www.thethingsnetwork.org/docs/lorawan/frequencies-by-country.html)

+Getting a version that includes a screen is optional, but highly recommended.
+
+## Firmware Installation
+
+Prebuilt binaries for the supported radios are available in our [releases](https://github.com/meshtastic/Meshtastic-esp32/releases). Your initial installation has to happen over USB from your Mac, Windows or Linux PC. Once our software is installed, all future software updates happen over bluetooth from your phone.
+
+Be **very careful** to install the correct load for your board. In particular the popular 'T-BEAM' radio from TTGO is not called 'TTGO-Lora' (that is a different board). So don't install the 'TTGO-Lora' build on a TBEAM, it won't work correctly.
+
+Please post comments on our [group chat](https://meshtastic.discourse.group/) if you have problems or successes.
+
+### Installing from a GUI - Windows and Mac
+
+1. Download and unzip the latest Meshtastic firmware [release](https://github.com/meshtastic/Meshtastic-esp32/releases).
+2. Download [ESPHome Flasher](https://github.com/esphome/esphome-flasher/releases) (either x86-32bit Windows or x64-64 bit Windows).
+3. Connect your radio to your USB port and open ESPHome Flasher.
+4. If your board is not showing under Serial Port then you likely need to install the drivers for the CP210X serial chip. In Windows you can check by searching “Device Manager” and ensuring the device is shown under “Ports”.
+5. If there is an error, download the drivers [here](https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers), then unzip and run the Installer application.
+6. In ESPHome Flasher, refresh the serial ports and select your board.
+7. Browse to the previously downloaded firmware and select the correct firmware based on the board type, country and frequency.
+8. Select Flash ESP.
+9. Once complete, “Done! Flashing is complete!” will be shown.
+10. Debug messages sent from the Meshtastic device can be viewed with a terminal program such as [PuTTY](https://www.putty.org/) (Windows only). Within PuTTY, click “Serial”, enter the “Serial line” com port (can be found at step 4), enter “Speed” as 921600, then click “Open”.
+
+### Installing from a commandline
+
+These instructions currently require a few commmand lines, but it should be pretty straightforward.
+
+1. Install "pip". Pip is the python package manager we use to get the esptool installer app. Instructions [here](https://www.makeuseof.com/tag/install-pip-for-python/). If you are using OS-X, see these [special instructions](docs/software/install-OSX.md).
+2. Run "pip install --upgrade esptool" to get esptool installed on your machine.
+3. Connect your radio to your USB port.
+4. Confirm that your device is talking to your PC by running "esptool.py chip_id". The Heltec build also works on the TTGO LORA32 radio. You should see something like:
 
-1. Purchase a radio (see above) with the correct frequencies for your country (915MHz for US or JP, 470MHz for CN, 870MHz for EU).

+We offer a [python API](https://github.com/meshtastic/Meshtastic-python) that makes it easy to use these devices to provide mesh networking for your custom projects.
 
 # Development
-The following sections are probably only interesting if you want to join us in developing the software.  
 
-## Power measurements
-Since one of the main goals of this project is long battery life, it is important to consider that in our software/protocol design.  Based on initial measurements it seems that the current code should run about three days between charging, and with a bit more software work (see the [TODO list](TODO.md)) a battery life of eight days should be quite doable.  Our current power measurements/model is in [this spreadsheet](https://docs.google.com/spreadsheets/d/1ft1bS3iXqFKU8SApU8ZLTq9r7QQEGESYnVgdtvdT67k/edit?usp=sharing).
+We'd love to have you join us on this merry little project. Please see our [development documents](./docs/software/sw-design.md) and [join us in our discussion forum](https://meshtastic.discourse.group/).
 
-## Build instructions
-This project uses the simple PlatformIO build system. You can use the IDE, but for brevity
-in these instructions I describe use of their command line tool.
+# Credits
 
-1. Purchase a suitable radio (see above)
-2. Install [PlatformIO](https://platformio.org/platformio-ide)
-3. Download this git repo and cd into it
-4. Plug the radio into your USB port
-4. Type "pio run -t upload" (This command will fetch dependencies, build the project and install it on the board via USB)
-5. Platform IO also installs a very nice VisualStudio Code based IDE, see their [tutorial](https://docs.platformio.org/en/latest/tutorials/espressif32/arduino_debugging_unit_testing.html) if you'd like to use it
+This project is run by volunteers. We are a friendly group and welcome any contribution (code fixes, documentation, features, bug reports etc...).  We try to be good about listing contributor names in release notes, but it has become unwieldy for the main-devs to keep updating the list below and we've neglected it too long.  If you'd like your name included in this list please send a pull request to edit this README and simply add your line yourself.  Thank you very much for your help!

-Items to complete soon (next couple of alpha releases).
-
-* text messages are not showing on local screen if screen was on
-
-* The following three items are all the same:
- Have state machine properly enter deep sleep based on loss of mesh and phone comms.
- Default to enter deep sleep if no LORA received for two hours (indicates user has probably left the mesh).
- If the phone doesn't read fromradio mailbox within X seconds, assume the phone is gone and we can stop queing location msgs 
-for it (because it will redownload the nodedb when it comes back)
-
-* lower wait_bluetooth_secs to 30 seconds once we have the GPS power on (but GPS in sleep mode) across light sleep.  For the time
-being I have it set at 2 minutes to ensure enough time for a GPS lock from scratch.
-
-* retest BLE software update for both board types
-* report on wikifactory
-* send note to the guy who designed the cases
-* remeasure wake time power draws now that we run CPU down at 80MHz
-
-# Medium priority
-
-Items to complete before the first beta release.
-
-* check fcc rules on duty cycle.  we might not need to freq hop.  https://www.sunfiretesting.com/LoRa-FCC-Certification-Guide/
-* use fuse bits to store the board type and region.  So one load can be used on all boards
-* "AXP192 interrupt is not firing, remove this temporary polling of battery state"
-* make mesh aware network timing state machine (sync wake windows to gps time)
-* turn light sleep on aggressively (while lora is on but BLE off)
-* research and implement better mesh algorithm
-* the BLE stack is leaking about 200 bytes each time we go to light sleep
-* use gps sleep mode instead of killing its power (to allow fast position when we wake)
-* rx signal measurements -3 marginal, -9 bad, 10 great, -10 means almost unusable.  So scale this into % signal strength.  preferably as a graph, with an X indicating loss of comms.  
-* assign every "channel" a random shared 8 bit sync word (per 4.2.13.6 of datasheet) - use that word to filter packets before even checking CRC.  This will ensure our CPU will only wake for packets on our "channel"  
-* Note: we do not do address filtering at the chip level, because we might need to route for the mesh
-* Use the Periodic class for both position and user periodic broadcasts
-* make debug info screen show real data (including battery level & charging)
-* don't forward redundant pings or ping responses to the phone, it just wastes phone battery
-* don't treat north as up, instead adjust shown bearings for our guess at the users heading (i.e. subtract one from the other)
-* answer to pings (because some other user is looking at our nodeinfo) with our latest location
-* show radio and gps signal strength as an image
-* only BLE advertise for a short time after the screen is on and button pressed - to save power and prevent people for sniffing for our BT app.
-* use https://platformio.org/lib/show/1260/OneButton if necessary
-* make an about to sleep screen
-* don't send location packets if we haven't moved
-* scrub default radio config settings for bandwidth/range/speed
-* add basic crypto - https://github.com/chegewara/esp32-mbedtls-aes-test/blob/master/main/main.c https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation - use ECB at first (though it is shit) because it doesn't require us to send 16 bytes of IV with each packet.  Then OFB per example
-* override peekAtMessage so we can see any messages that pass through our node (even if not broadcast)?  would that be useful?
-* sendToMesh can currently block for a long time, instead have it just queue a packet for a radio freertos thread
-* How do avalanche beacons work?  Could this do that as well?  possibly by using beacon mode feature of the RF95?
-* use std::map<NodeInfo*, std::string> in node db
-* make a HAM build: yep - that's a great idea.  I'll add it to the TODO.  should be pretty painless - just a new frequency list, a bool to say 'never do encryption' and use hte callsign as that node's unique id.  -from Girts
-* add frequency hopping, dependent on the gps time, make the switch moment far from the time anyone is going to be transmitting
-* publish update articles on the web
-
-# Pre-beta priority
-
-During the beta timeframe the following improvements 'would be nice' (and yeah - I guess some of these items count as features, but it is a hobby project ;-) )
-
-* Figure out why the RF95 ISR is never seeing RH_RF95_VALID_HEADER, so it is not protecting our rx packets from getting stomped on by sends
-* use BLEDevice::setPower to lower our BLE transmit power - extra range doesn't help us, it costs amps and it increases snoopability
-* make an install script to let novices install software on their boards
-* fix the frequency error reading in the RF95 RX code (can't do floating point math in an ISR ;-) 
-* See CustomRF95::send and fix the problem of dropping partially received packets if we want to start sending
-* use variable length arduino Strings in protobufs (instead of current fixed buffers)
-* don't even power on bluetooth until we have some data to send to the android phone.  Most of the time we should be sleeping in a lowpower "listening for lora" only mode.  Once we have some packets for the phone, then power on bluetooth
-until the phone pulls those packets.  Ever so often power on bluetooth just so we can see if the phone wants to send some packets.  Possibly might need ULP processor to help with this wake process.
-* do hibernation mode to get power draw down to 2.5uA https://lastminuteengineers.com/esp32-sleep-modes-power-consumption/ 
-* make sure main cpu is not woken for packets with bad crc or not addressed to this node - do that in the radio hw
-* enable fast init inside the gps chip
-* triple check fcc compliance
-* pick channel center frequency based on name? "dolphin" would hash to 900Mhz, "cat" to 905MHz etc?  Or is that too opaque?
-* scan to find channels with low background noise?
-* share channel settings over Signal (or qr code) by embedding an an URL which is handled by the MeshUtil app.
-
-# Low priority
-
-Items after the first final candidate release.
-
-* split out the software update utility so other projects can use it.  Have the appload specify the URL for downloads.
-* Use CAD mode of the RF95 to automatically find low noise channels
-* read the PMU battery fault indicators and blink/led/warn user on screen
-* make a no bluetooth configured yet screen - include this screen in the loop if the user hasn't yet paired
-* the AXP debug output says it is trying to charge at 700mA, but the max I've seen is 180mA, so AXP registers probably need to be set to tell them the circuit can only provide 300mAish max. So that the low charge rate kicks in faster and we don't wear out batteries.
-* increase the max charging rate a bit for 18650s, currently it limits to 180mA (at 4V).  Work backwards from the 500mA USB limit (at 5V) and let the AXP charge at that rate.
-* if radio params change fundamentally, discard the nodedb
-* discard very old nodedb records (> 1wk)
-* using the genpartitions based table doesn't work on TTGO so for now I stay with my old memory map
-* We let anyone BLE scan for us (FIXME, perhaps only allow that until we are paired with a phone and configured) 
-* use two different buildenv flags for ttgo vs lora32. https://docs.platformio.org/en/latest/ide/vscode.html#key-bindings
-* sim gps data for testing nodes that don't have hardware
-* do debug serial logging to android over bluetooth
-* break out my bluetooth OTA software as a seperate library so others can use it
-* Heltec LoRa32 has 8MB flash, use a bigger partition table if needed - TTGO is 4MB but has PSRAM
-* add a watchdog timer
-* fix GPS.zeroOffset calculation it is wrong
-* handle millis() rollover in GPS.getTime - otherwise we will break after 50 days
-* reneable the bluetooth battery level service on the T-BEAM, because we can read battery level there
-* report esp32 device code bugs back to the mothership via android
-
-# Done
-
-* change the partition table to take advantage of the 4MB flash on the wroom: http://docs.platformio.org/en/latest/platforms/espressif32.html#partition-tables
-* wrap in nice MeshRadio class
-* add mesh send & rx
-* make message send from android go to service, then to mesh radio
-* make message receive from radio go through to android
-* test loopback tx/rx path code without using radio
-* notify phone when rx packets arrive, currently the phone polls at startup only
-* figure out if we can use PA_BOOST - yes, it seems to be on both boards
-* implement new ble characteristics
-* have MeshService keep a node DB by sniffing user messages
-* have a state machine return the correct FromRadio packet to the phone, it isn't always going to be a MeshPacket.  Do a notify on fromnum to force the radio to read our state machine generated packets
-* send my_node_num when phone sends WantsNodes
-* have meshservice periodically send location data on mesh (if device has a GPS)
-* implement getCurrentTime() - set based off gps but then updated locally
-* make default owner record have valid usernames
-* message loop between node 0x28 and 0x7c
-* check in my radiolib fixes
-* figure out what is busted with rx
-* send our owner info at boot, reply if we see anyone send theirs
-* add manager layers
-* confirm second device receives that gps message and updates device db
-* send correct hw vendor in the bluetooth info - needed so the android app can update different radio models
-* correctly map nodeids to nodenums, currently we just do a proof of concept by always doing a broadcast
-* add interrupt detach/sleep mode config to lora radio so we can enable deepsleep without panicing
-* make jtag work on second board
-* implement regen owner and radio prefs
-* use a better font
-* make nice screens (boot, about to sleep, debug info (gps signal, #people), latest text, person info - one frame per person on network)
-* turn framerate from ui->state.frameState to 1 fps (or less) unless in transition
-* switch to my gui layout manager
-* make basic gui. different screens: debug, one page for each user in the user db, last received text message
-* make button press cycle between screens
-* save our node db on entry to sleep
-* fix the logo
-* sent/received packets (especially if a node was just reset) have variant of zero sometimes - I think there is a bug (race-condtion?) in the radio send/rx path.
-* DONE dynamic nodenum assignment tasks
-* make jtag debugger id stable: https://askubuntu.com/questions/49910/how-to-distinguish-between-identical-usb-to-serial-adapters
-* reported altitude is crap
-* good tips on which bands might be more free https://github.com/TheThingsNetwork/ttn/issues/119
-* finish power measurements (GPS on during sleep vs LCD on during sleep vs LORA on during sleep) and est battery life
-* make screen sleep behavior work
-* make screen advance only when a new node update arrives, a new text arrives or the user presses a button, turn off screen after a while
-* after reboot, channel number is getting reset to zero! fix!
-* send user and location events much less often
-* send location (or if not available user) when the user wakes the device from display sleep (both for testing and to improve user experience)
-* make real implementation of getNumOnlineNodes
-* very occasionally send our position and user packet based on the schedule in the radio info (if for nothing else so that other nodes update last_seen)
-* show real text info on the text screen
-* apply radio settings from android land
-* cope with nodes that have 0xff or 0x00 as the last byte of their mac
-* allow setting full radio params from android
-* add receive timestamps to messages, inserted by esp32 when message is received but then shown on the phone
-* update build to generate both board types
-* have node info screen show real info (including distance and heading)
-* blink the power led less often
-* have radiohead ISR send messages to RX queue directly, to allow that thread to block until we have something to send
-* move lora rx/tx to own thread and block on IO
-* keep our pseudo time moving forward even if we enter deep sleep (use esp32 rtc)
-* for non GPS equipped devices, set time from phone
-* GUI on oled hangs for a few seconds occasionally, but comes back
-* update local GPS position (but do not broadcast) at whatever rate the GPS is giving it
-* don't send our times to other nodes
-* don't trust times from other nodes
-* draw compass rose based off local walking track
-* add requestResponse optional bool - use for location broadcasts when sending tests
-* post sample video to signal forum
-* support non US frequencies
-* send pr https://github.com/ThingPulse/esp8266-oled-ssd1306 to tell them about this project
-* document rules for sleep wrt lora/bluetooth/screen/gps.  also: if I have text messages (only) for the phone, then give a few seconds in the hopes BLE can get it across before we have to go back to sleep.
-* wake from light sleep as needed for our next scheduled periodic task (needed for gps position broadcasts etc)
-* turn bluetooth off based on our sleep policy
-* blink LED while in LS sleep mode
-* scrolling between screens based on press is busted
-* Use Neo-M8M API to put it in sleep mode (on hold until my new boards arrive)
-* update the prebuilt bins for different regulatory regions
-* don't enter NB state if we've recently talked to the phone (to prevent breaking syncing or bluetooth sw update)
-* have sw update prevent BLE sleep
-* manually delete characteristics/descs
-* leave lora receiver always on
-* protobufs are sometimes corrupted after sleep!
-* stay awake while charging
-* check gps battery voltage
-* if a position report includes ground truth time and we don't have time yet, set our clock from that.  It is better than nothing.

-# What is Meshtastic?
-
-Meshtastic is a project that lets you use
-inexpensive ($30 ish) GPS radios as an extensible, super long battery life mesh GPS communicator.  These radios are great for hiking, skiing, paragliding - 
-essentially any hobby where you don't have reliable internet access.  Each member of your private mesh can always see the location and distance of all other
-members and any text messages sent to your group chat.
-
-The radios automatically create a mesh to forward packets as needed, so everyone in the group can receive messages from even the furthest member.  The radios
-will optionally work with your phone, but no phone is required.
-
-### Uses
-
-* Outdoor sports where cellular coverage is limited. (Hiking, Skiing, Boating, Paragliding, Gliders etc..)
-* Applications where closed source GPS communicators just won't cut it (it is easy to add features for glider pilots etc...)
-* Secure long-range communication within groups without depending on cellular providers
-* Finding your lost kids ;-)
-
-[![Youtube video demo](desk-video-screenshot.png)](https://www.youtube.com/watch?v=WlNbMbVZlHI "Meshtastic early demo")
-
-### Features
-Not all of these features are fully implemented yet - see below.  But they should be in by the time we decide to call this project beta (three months?)
-
-* Very long battery life (should be about eight days with the beta software)
-* Built in GPS and [LoRa](https://en.wikipedia.org/wiki/LoRa) radio, but we manage the radio automatically for you
-* Long range - a few miles per node but each node will forward packets as needed
-* Shows direction and distance to all members of your channel
-* Directed or broadcast text messages for channel members
-* Open and extensible codebase supporting multiple hardware vendors - no lock in to one vendor
-* Communication API for bluetooth devices (such as our Android app) to use the mesh.  So if you have some application that needs long range low power networking, this might work for you.
-* Eventually (within a couple of months) we should have a modified version of Signal that works with this project.
-* Very easy sharing of private secured channels.  Just share a special link or QR code with other users and they can join your encrypted mesh
- 
-This project is currently in early alpha - if you have questions please join our chat [![Join the chat at https://gitter.im/Meshtastic/community](https://badges.gitter.im/Meshtastic/community.svg)](https://gitter.im/Meshtastic/community?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge).
-
-This software is 100% open source and developed by a group of hobbyist experimenters.  No warranty is provided, if you'd like to improve it - we'd love your help.  Please post in the [chat](https://gitter.im/Meshtastic/community).  
-
-# Updates
-
-* 02/25/2020 - 0.0.4 of the Android app is released.  This is a very early alpha, see below to join the alpha-testers group.
-* 02/23/2020 - 0.0.4 release.  Still very bleeding edge but much closer to the final power management, a charged T-BEAM should run for many days with this load.  If you'd like to try it, we'd love your feedback.  Click [here](https://github.com/geeksville/Meshtastic-esp32/blob/master/README.md) for instructions.
-* 02/20/2020 - Our first alpha release (0.0.3) of the radio software is ready for early users.  
-
-## Meshtastic Android app
-Once out of alpha the companion Android application will be released here:
-
-[![Download at https://play.google.com/store/apps/details?id=com.geeksville.mesh](https://play.google.com/intl/en_us/badges/static/images/badges/en_badge_web_generic.png)](https://play.google.com/store/apps/details?id=com.geeksville.mesh&referrer=utm_source%3Dhomepage%26anid%3Dadmob)
-
-But if you want the bleeding edge app now, we'd love to have your help testing.  Three steps to opt-in to the alpha- test:
-
-1. Join [this Google group](https://groups.google.com/forum/#!forum/meshtastic-alpha-testers) with the account you use in Google Play.
-2. Go to this [URL](https://play.google.com/apps/testing/com.geeksville.mesh) to opt-in to the alpha test.
-3. If you encounter any problems or have questions, post in our gitter chat and we'll help.
-
-If you'd like to help with development, the source code is [on github](https://github.com/geeksville/Meshtastic-Android).
-
-## Supported hardware
-We currently support two brands of radios.  The [TTGO T-Beam](https://www.aliexpress.com/item/4000119152086.html) and the [Heltec LoRa 32](https://heltec.org/project/wifi-lora-32/).  Most users should buy the T-Beam and a 18650 battery (total cost less than $35).  Make
-sure to buy the frequency range which is legal for your country.  For the USA, you should buy the 915MHz version.  Getting a version that include a screen
-is optional, but highly recommended.
-
-Instructions for installing prebuilt firmware can be found [here](https://github.com/geeksville/Meshtastic-esp32/blob/master/README.md).

-# Disclaimers
-
-This project is still pretty young but moving at a pretty good pace.  Not all features are fully implemented in the current alpha builds.
-Most of these problems should be solved by the beta release:
-
-* We don't make these devices and they haven't been tested by UL or the FCC.  If you use them you are experimenting and we can't promise they won't burn your house down ;-)
-* Encryption is turned off for now
-* A number of (straightforward) software work items have to be completed before battery life matches our measurements, currently battery life is about two days.  Join us on chat if you want the spreadsheet of power measurements/calculations.
-* The current Android GUI is pretty ugly still
-* The Android API needs to be documented better
-* The Bluetooth API needs to be documented better 
-* The mesh protocol is turned off for now, currently we only send packets one hop distant
-* No one has written an iOS app yet ;-)
-
-For more details see the [device software TODO](https://github.com/geeksville/Meshtastic-esp32/blob/master/TODO.md) or the [Android app TODO](https://github.com/geeksville/Meshtastic-Android/blob/master/TODO.md).

-# Rules for sleep
-
-## States
-
-From lower to higher power consumption.
-
-* Super-deep-sleep (SDS) - everything is off, CPU, radio, bluetooth, GPS.  Only wakes due to timer or button press
-  onEntry: setBluetoothOn(false), call doDeepSleep
-  onExit: (standard bootup code, starts in DARK)
-
-* deep-sleep (DS) - CPU is off, radio is on, bluetooth and GPS is off.  Note: This mode is never used currently, because it only saves 1.5mA vs light-sleep
-  (Not currently used)
-
-* light-sleep (LS) - CPU is suspended (RAM stays alive), radio is on, bluetooth is off, GPS is off.  Note: currently GPS is not turned 
-off during light sleep, but there is a TODO item to fix this.
-  onEntry: setBluetoothOn(false), setGPSPower(false), doLightSleep()
-  onIdle: (if we wake because our led blink timer has expired) blink the led then go back to sleep until we sleep for ls_secs
-  onExit: setGPSPower(true), start trying to get gps lock: gps.startLock(), once lock arrives service.sendPosition(BROADCAST)
-
-* No bluetooth (NB) - CPU is running, radio is on, GPS is on but bluetooth is off, screen is off.
-  onEntry: setBluetoothOn(false)
-  onExit: 
-
-* running dark (DARK) - Everything is on except screen
-  onEntry: setBluetoothOn(true)
-  onExit: 
-
-* full on (ON) - Everything is on
-  onEntry: setBluetoothOn(true), screen.setOn(true)
-  onExit: screen.setOn(false)
-
-## Behavior
-
-### events that increase CPU activity
-
-* At cold boot: The initial state (after setup() has run) is DARK
-* While in DARK: if we receive EVENT_BOOT, transition to ON (and show the bootscreen).  This event will be sent if we detect we woke due to reset (as opposed to deep sleep)
-* While in LS: Once every position_broadcast_secs (default 15 mins) - the unit will wake into DARK mode and broadcast a "networkPing" (our position) and stay alive for wait_bluetooth_secs (default 30 seconds).  This allows other nodes to have a record of our last known position if we go away and allows a paired phone to hear from us and download messages.
-* While in LS: Every send_owner_interval (defaults to 4, i.e. one hour), when we wake to send our position we _also_ broadcast our owner.  This lets new nodes on the network find out about us or correct duplicate node number assignments.
-* While in LS/NB/DARK: If the user presses a button (EVENT_PRESS) we go to full ON mode for screen_on_secs (default 30 seconds).  Multiple presses keeps resetting this timeout
-* While in LS/NB/DARK: If we receive new text messages (EVENT_RECEIVED_TEXT_MSG), we go to full ON mode for screen_on_secs (same as if user pressed a button)
-* While in LS: while we receive packets on the radio (EVENT_RECEIVED_PACKET) we will wake and handle them and stay awake in NB mode for min_wake_secs (default 10 seconds) 
-* While in NB: If we do have packets the phone (EVENT_PACKETS_FOR_PHONE) would want we transition to DARK mode for wait_bluetooth secs.
-* While in DARK/ON: If we receive EVENT_BLUETOOTH_PAIR we transition to ON and start our screen_on_secs timeout
-* While in NB/DARK/ON: If we receive EVENT_NODEDB_UPDATED we transition to ON (so the new screen can be shown)
-* While in DARK: While the phone talks to us over BLE (EVENT_CONTACT_FROM_PHONE) reset any sleep timers and stay in DARK (needed for bluetooth sw update and nice user experience if the user is reading/replying to texts)
-
-### events that decrease cpu activity
-
-* While in ON: If PRESS event occurs, reset screen_on_secs timer and tell the screen to handle the pess
-* While in ON: If it has been more than screen_on_secs since a press, lower to DARK
-* While in DARK: If time since last contact by our phone exceeds phone_timeout_secs (15 minutes), we transition down into NB mode
-* While in DARK or NB: If nothing above is forcing us to stay in a higher mode (wait_bluetooth_secs, min_wake_secs) we will lower down to LS state
-* While in into LS: If either phone_sds_timeout_secs (default 1 hr) or mesh_sds_timeout_secs (default 1 hr) are exceeded we will lower into SDS mode for sds_secs (default 1 hr) (or a button press).  
-* Any time we enter LS mode: We stay in that mode for ls_secs (default 1 hr) (or until an interrupt, button press)
-
-TODO: Eventually these scheduled intervals should be synchronized to the GPS clock, so that we can consider leaving the lora receiver off to save even more power.
-TODO: In NB mode we should put cpu into light sleep any time we really aren't that busy (without declaring LS state) - i.e. we should leave GPS on etc...
-
-# Low power consumption tasks
-
-General ideas to hit the power draws our spreadsheet predicts.  Do the easy ones before beta, the last 15% can be done after 1.0.
-
-* don't even power on the gps until someone else wants our position, just stay in lora deep sleep until press or rxpacket (except for once an hour updates)
-* (possibly bad idea - better to have lora radio always listen - check spreadsheet) have every node wake at the same tick and do their position syncs then go back to deep sleep
-* lower BT announce interval to save battery
-* change to use RXcontinuous mode and config to drop packets with bad CRC (see section 6.4 of datasheet) - I think this is already the case
-* have mesh service run in a thread that stays blocked until a packet arrives from the RF95
-* platformio sdkconfig CONFIG_PM and turn on modem sleep mode
-* keep cpu 100% in deepsleep until irq from radio wakes it.  Then stay awake for 30 secs to attempt delivery to phone.  
-* use https://lastminuteengineers.com/esp32-sleep-modes-power-consumption/ association sleep pattern to save power - but see https://github.com/espressif/esp-idf/issues/2070 and https://esp32.com/viewtopic.php?f=13&t=12182 it seems with BLE on the 'easy' draw people are getting is 80mA
-* stop using loop() instead use a job queue and let cpu sleep
-* measure power consumption and calculate battery life assuming no deep sleep
-* do lowest sleep level possible where BT still works during normal sleeping, make sure cpu stays in that mode unless lora rx packet happens, bt rx packet happens or button press happens
-* optionally do lora messaging only during special scheduled intervals (unless nodes are told to go to low latency mode), then deep sleep except during those intervals - before implementing calculate what battery life would be with  this feature
-* see section 7.3 of https://cdn.sparkfun.com/assets/learn_tutorials/8/0/4/RFM95_96_97_98W.pdf and have hope radio wake only when a valid packet is received.  Possibly even wake the ESP32 from deep sleep via GPIO.
-* never enter deep sleep while connected to USB power (but still go to other low power modes)
-* when main cpu is idle (in loop), turn cpu clock rate down and/or activate special sleep modes.  We want almost everything shutdown until it gets an interrupt.
-
-# Mesh broadcast algoritm
-
-FIXME - instead look for standard solutions.  this approach seems really suboptimal, because too many nodes will try to rebroast.  If
-all else fails could always use the stock radiohead solution - though super inefficent.
-
-## approach 1
-
-* send all broadcasts with a TTL
-* periodically(?) do a survey to find the max TTL that is needed to fully cover the current network.
-* to do a study first send a broadcast (maybe our current initial user announcement?) with TTL set to one (so therefore no one will rebroadcast our request)
-* survey replies are sent unicast back to us (and intervening nodes will need to keep the route table that they have built up based on past packets)
-* count the number of replies to this TTL 1 attempt.  That is the number of nodes we can reach without any rebroadcasts
-* repeat the study with a TTL of 2 and then 3.  stop once the # of replies stops going up.
-* it is important for any node to do listen before talk to prevent stomping on other rebroadcasters...
-* For these little networks I bet a max TTL would never be higher than 3?
-
-## approach 2
-
-* send a TTL1 broadcast, the replies let us build a list of the nodes (stored as a bitvector?) that we can see (and their rssis)
-* we then broadcast out that bitvector (also TTL1) asking "can any of ya'll (even indirectly) see anyone else?"
-* if a node can see someone I missed (and they are the best person to see that node), they reply (unidirectionally) with the missing nodes and their rssis (other nodes might sniff (and update their db) based on this reply but they don't have to)
-* given that the max number of nodes in this mesh will be like 20 (for normal cases), I bet globally updating this db of "nodenums and who has the best rssi for packets from that node" would be useful
-* once the global DB is shared, when a node wants to broadcast, it just sends out its broadcast . the first level receivers then make a decision "am I the best to rebroadcast to someone who likely missed this packet?" if so, rebroadcast
-
-## approach 3
-
-* when a node X wants to know other nodes positions, it broadcasts its position with want_replies=true.  Then each of the nodes that received that request broadcast their replies (possibly by using special timeslots?)
-* all nodes constantly update their local db based on replies they witnessed.
-* after 10s (or whatever) if node Y notices that it didn't hear a reply from node Z (that Y has heard from recently ) to that initial request, that means Z never heard the request from X.  Node Y will reply to X on Z's behalf.
-* could this work for more than one hop?  Is more than one hop needed?  Could it work for sending messages (i.e. for a msg sent to Z with want-reply set). 
-
-## approach 4
-
-look into the literature for this idea specifically.
-
-* don't view it as a mesh protocol as much as a "distributed db unification problem".  When nodes talk to nearby nodes they work together
-to update their nodedbs.  Each nodedb would have a last change date and any new changes that only one node has would get passed to the 
-other node.  This would nicely allow distant nodes to propogate their position to all other nodes (eventually).
-* handle group messages the same way, there would be a table of messages and time of creation.
-* when a node has a new position or message to send out, it does a broadcast.  All the adjacent nodes update their db instantly (this handles 90% of messages I'll bet).  
-* Occasionally a node might broadcast saying "anyone have anything newer than time X?"  If someone does, they send the diffs since that date.
-* essentially everything in this variant becomes broadcasts of "request db updates for >time X - for _all_ or for a particular nodenum" and nodes sending (either due to request or because they changed state) "here's a set of db updates".  Every node is constantly trying to
-build the most recent version of reality, and if some nodes are too far, then nodes closer in will eventually forward their changes to the distributed db.
-* construct non ambigious rules for who broadcasts to request db updates.  ideally the algorithm should nicely realize node X can see most other nodes, so they should just listen to all those nodes and minimize the # of broadcasts. the distributed picture of nodes rssi could be useful here?
-* possibly view the BLE protocol to the radio the same way - just a process of reconverging the node/msgdb database.

+* DONE don't send packets we received from the phone BACK TOWARDS THE PHONE (possibly use fromnode 0 for packets the phone sends?)
+* DONE fix 1.1.50 android debug panel display
+* DONE test android channel setting
+* DONE release to users
+* DONE warn in android app about unset regions
+* DONE use set-channel from android
+* DONE add gui in android app for setting region
+* DONE clean up python channel usage
+* DONE use bindToChannel to limit admin access for remote nodes
+* DONE move channels and radio config out of device settings
+* DONE test remote info and remote settings changes
+* make python tests more exhaustive
+* DONE pick default random admin key
+* exclude admin channels from URL?
+* make a way to share just secondary channels via URL
+* generalize the concept of "shortstrings" use it for both PSKs and well known channel names.  Possibly use a ShortString class.
+* use single byte 'well known' channel names for admin, gpio, etc...
+* use presence of gpio channel to enable gpio ops, same for serial etc...
+* DONE restrict gpio & serial & settings operations to the admin channel (unless local to the current node)
+* DONE add channel restrictions for plugins (and restrict routing plugin to the "control" channel)
+* stress test multi channel
+* DONE investigate @mc-hamster report of heap corruption
+* DONE use set-user from android
+* untrusted users should not be allowed to provide bogus times (via position broadcasts) to the rest of the mesh.  Invent a new lowest quality notion of UntrustedTime.
+* use portuino TCP connection to debug with python API
+* document the relationship between want_response (indicating remote node received it) and want_ack (indicating that this message should be sent reliably - and also get acks from the first rx node and naks if it is never delivered)
+* DONE android should stop fetching channels once we've reached our first empty channel definition (hasSettings == true)
+* DONE warn in python api if we are too new to talk to the device code
+* DONE make a post warning about 1.2, telling how to stay on old android & python clients.  link to this from the android dialog message and python version warning.
+* DONE "FIXME - move the radioconfig/user/channel READ operations into SettingsMessage as well"
+* DONE scrub protobufs to make sure they are absoloute minimum wiresize (in particular Data, ChannelSets and positions)
+* DONE change syncword (now ox2b)
+* allow chaning packets in single transmission - to increase airtime efficiency and amortize packet overhead
+* DONE move most parts of meshpacket into the Data packet, so that we can chain multiple Data for sending when they all have a common destination and key.
+* when selecting a MeshPacket for transmit, scan the TX queue for any Data packets we can merge together as a WirePayload.  In the low level send/rx code expand that into multiple MeshPackets as needed (thus 'hiding' from MeshPacket that over the wire we send multiple datapackets
+* DONE confirm we are still calling the plugins for messages inbound from the phone (or generated locally)
+* DONE confirm we are still multi hop routing flood broadcasts
+* DONE confirm we are still doing resends on unicast reliable packets
+* add history to routed packets: https://meshtastic.discourse.group/t/packet-source-tracking/2764/2
+* add support for full DSR unicast delivery
+* DONE move acks into routing
+* DONE make all subpackets different versions of data
+* DONE move routing control into a data packet
+* have phoneapi done via plugin (will allow multiple simultaneous API clients - stop disabling BLE while using phone API)
+* use reference counting and dynamic sizing for meshpackets. - use https://docs.microsoft.com/en-us/cpp/cpp/how-to-create-and-use-shared-ptr-instances?view=msvc-160 (already used in arduino)
+* let multiple PhoneAPI endpoints work at once
+* allow multiple simultaneous bluetooth connections (create the bluetooth phoneapi instance dynamically based on client id)
+* DONE figure out how to add micro_delta to position, make it so that phone apps don't need to understand it?
+* only send battery updates a max of once a minute
+* DONE add python channel selection for sending
+* DONE record recevied channel in meshpacket
+* test remote settings operations (confirm it works 3 hops away)
+* DONE make a primaryChannel global and properly maintain it when the phone sends setChannel
+* DONE move setCrypto call into packet send and packet decode code
+* implement 'small location diffs' change
+* move battery level out of position? 
+* consider "A special exception (FIXME, not sure if this is a good idea) - packets that arrive on the local interface 
+  are allowed on any channel (this lets the local user do anything)."  Probably by adding a "secure_local_interface" settings bool.
+* DOUBLE CHECK android app can still upgrade 1.1 and 1.0 loads
+ 
+For app cleanup:
+
+* don't store redundant User admin or position broadcasts in the ToPhone queue (only keep one per sending node per proto type, and only most recent)
+* use structured logging to kep logs in ram.  Also send logs as packets to api clients
+* DONE writeup nice python options docs (common cases, link to protobuf docs)
+* have android app link to user manual
+* DONE only do wantReplies once per packet type, if we change network settings force it again
+* update positions and nodeinfos based on packets we just merely witness on the mesh.  via isPromsciousPort bool, remove sniffing
+* DONE make device build always have a valid version
+* DONE do fixed position bug https://github.com/meshtastic/Meshtastic-device/issues/536
+* DONE check build guide
+* DONE write devapi user guide
+* DONE update android code: https://developer.android.com/topic/libraries/view-binding/migration
+* DONE test GPIO watch
+* DONE set --set-chan-fast, --set-chan-default
+* writeup docs on gpio 
+* DONE make python ping command
+* DONE make hello world example service
+* DONE have python tool check max packet size before sending to device
+* DONE if request was sent reliably, send reply reliably
+* DONE require a recent python api to talk to these new device loads
+* DONE require a recent android app to talk to these new device loads
+* DONE fix handleIncomingPosition
+* DONE move want_replies handling into plugins
+* DONE on android for received positions handle either old or new positions / user messages
+* DONE on android side send old or new positions as needed / user messages
+* DONE test python side handle new position/user messages
+* DONE make a gpio example. --gpiowrb 4 1, --gpiord 0x444, --gpiowatch 0x3ff
+* DONE fix position sending to use new plugin
+* DONE Add SinglePortNumPlugin - as the new most useful baseclass
+* DONE move positions into regular data packets (use new app framework)
+* DONE move user info into regular data packets (use new app framework)
+* DONE test that positions, text messages and user info still work
+* DONE test that position, text messages and user info work properly with new android app and old device code
+* DONE do UDP tunnel
+* DONE fix the RTC drift bug
+* move python ping functionality into device, reply with rxsnr info
+* use channels for gpio security https://github.com/meshtastic/Meshtastic-device/issues/104
+* MeshPackets for sending should be reference counted so that API clients would have the option of checking sent status (would allow removing the nasty 30 sec timer in gpio watch sending)
+
+For high speed/lots of devices/short range tasks:
+
+- When guessing numhops for sending: if I've heard from many local (0 hop neighbors) decrease hopcount by 2 rather than 1. 
+This should nicely help 'router' nodes do the right thing when long range, or if there are many local nodes for short range.
+- fix timeouts/delays to be based on packet length at current radio settings
+
+* update faq with antennas https://meshtastic.discourse.group/t/range-test-ideas-requested/738/2
+* update faq on recommended android version and phones

+# Old docs to merge
+
+MESH RADIO PROTOCOL
+
+Old TODO notes on the mesh radio protocol, merge into real docs someday...
+
+for each named group we have a pre-shared key known by all group members and
+wrapped around the device. you can only be in one group at a time (FIXME?!) To
+join the group we read a qr code with the preshared key and ParamsCodeEnum. that
+gets sent via bluetooth to the device.  ParamsCodeEnum maps to a set of various
+radio params (regulatory region, center freq, SF, bandwidth, bitrate, power
+etc...) so all members of the mesh can have their radios set the same way.
+
+once in that group, we can talk between 254 node numbers.
+to get our node number (and announce our presence in the channel) we pick a
+random node number and broadcast as that node with WANT-NODENUM(my globally
+unique name).  If anyone on the channel has seen someone _else_ using that name
+within the last 24 hrs(?) they reply with DENY-NODENUM. Note: we might receive
+multiple denies.  Note: this allows others to speak up for some other node that
+might be saving battery right now. Any time we hear from another node (for any
+message type), we add that node number to the unpickable list.  To dramatically
+decrease the odds a node number we request is already used by someone. If no one
+denies within TBD seconds, we assume that we have that node number.  As long as
+we keep talking to folks at least once every 24 hrs, others should remember we
+have it.
+
+Once we have a node number we can broadcast POSITION-UPDATE(my globally unique
+name, lat, lon, alt, amt battery remaining).  All receivers will use this to a)
+update the mapping of who is at what node nums, b) the time of last rx, c)
+position.  If we haven't heard from that node in a while we reply to that node
+(only) with our current POSITION_UPDATE state - so that node (presumably just
+rejoined the network) can build a map of all participants.
+
+We will periodically broadcast POSITION-UPDATE as needed based on distance moved
+or a periodic minimum heartbeat.
+
+If user wants to send a text they can SEND_TEXT(dest user, short text message).
+Dest user is a node number, or 0xff for broadcast.
+
+# Medium priority
+
+Items to complete before 1.0.
+
+# Post 1.0 ideas
+
+- finish DSR for unicast
+- check fcc rules on duty cycle. we might not need to freq hop. https://www.sunfiretesting.com/LoRa-FCC-Certification-Guide/ . Might need to add enforcement for europe though.
+- make a no bluetooth configured yet screen - include this screen in the loop if the user hasn't yet paired
+- if radio params change fundamentally, discard the nodedb
+- re-enable the bluetooth battery level service on the T-BEAM
+- provide generalized (but slow) internet message forwarding service if one of our nodes has internet connectivity (MQTT) [ Not a requirement but a personal interest ]
+
+# Low priority ideas
+
+Items after the first final candidate release.
+
+- implement nimble battery level service
+- Nimble implement device info service remaining fields (hw version etc)
+- Turn on RPA addresses for the device side in Nimble
+- Try to teardown less of the Nimble protocol stack across sleep
+- dynamic frequency scaling could save a lot of power on ESP32, but it seems to corrupt uart (even with ref_tick set correctly)
+- Change back to using a fixed sized MemoryPool rather than MemoryDynamic (see bug #149)
+- scan to find channels with low background noise? (Use CAD mode of the RF95 to automatically find low noise channels)
+- If the phone doesn't read fromradio mailbox within X seconds, assume the phone is gone and we can stop queing location msgs
+  for it (because it will redownload the nodedb when it comes back)
+- add frequency hopping, dependent on the gps time, make the switch moment far from the time anyone is going to be transmitting
+- assign every "channel" a random shared 8 bit sync word (per 4.2.13.6 of datasheet) - use that word to filter packets before even checking CRC. This will ensure our CPU will only wake for packets on our "channel"
+- the BLE stack is leaking about 200 bytes each time we go to light sleep
+- use fuse bits to store the board type and region. So one load can be used on all boards
+- Don't store position packets in the to phone fifo if we are disconnected. The phone will get that info for 'free' when it
+  fetches the fresh nodedb.
+- Use the RFM95 sequencer to stay in idle mode most of the time, then automatically go to receive mode and automatically go from transmit to receive mode. See 4.2.8.2 of manual.
+- Use fixed32 for node IDs, packetIDs, successid, failid, and lat/lon - will require all nodes to be updated, but make messages slightly smaller.
+- add "store and forward" support for messages, or move to the DB sync model. This would allow messages to be eventually delivered even if nodes are out of contact at the moment.
+- use variable length Strings in protobufs (instead of current fixed buffers). This would save lots of RAM
+- use BLEDevice::setPower to lower our BLE transmit power - extra range doesn't help us, it costs amps and it increases snoopability
+- make a HAM build: just a new frequency list, a bool to say 'never do encryption' and use hte callsign as that node's unique id. -from Girts
+- don't forward redundant pings or ping responses to the phone, it just wastes phone battery
+- don't send location packets if we haven't moved significantly
+- scrub default radio config settings for bandwidth/range/speed
+- show radio and gps signal strength as an image
+- only BLE advertise for a short time after the screen is on and button pressed - to save power and prevent people for sniffing for our BT app.
+- make mesh aware network timing state machine (sync wake windows to gps time) - this can save LOTS of battery
+- split out the software update utility so other projects can use it. Have the appload specify the URL for downloads.
+- read the PMU battery fault indicators and blink/led/warn user on screen
+- discard very old nodedb records (> 1wk)
+- handle millis() rollover in GPS.getTime - otherwise we will break after 50 days
+- report esp32 device code bugs back to the mothership via android
+- change BLE bonding to something more secure. see comment by pSecurity->setAuthenticationMode(ESP_LE_AUTH_BOND)
+
+Changes related to wifi support on ESP32:
+
+- iram space: https://esp32.com/viewtopic.php?t=8460
+- set https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/external-ram.html spi ram bss
+- figure out if iram or bluetooth classic caused ble problems
+- post bug on esp32-arduino with BLE bug findings
+
+# Spinoff project ideas
+
+- an open source version of https://www.burnair.ch/skynet/
+- a paragliding app like http://airwhere.co.uk/
+- How do avalanche beacons work? Could this do that as well? possibly by using beacon mode feature of the RF95?
